VJINDOW SCREEN.

Application filed November This invention relates to window screens, the imprm'ements in general applying to screens of the adjustable, or non-adjustable types.

An important feature of the invention comprises a screen which is adapted to fit between the guide stripson the opposite sides of the window frame outside of the lower sash, such screen being mounted to swing or tilt inwardly, and being removable while in such tilted position. An advantage of this construction and arrangement is that the screen may be located outside of and may fit against the outer face of the lower portion of the sash, thus permitting the sash to be raised or lowered without removing the screen.

Another important feature of the inven tion is comprised in a screen of the character referred to having facility for easy removal from or insertion into position in the window frame, and without the use of the usual guide strips, which frequently swell from dampness, rendering the movement of the 5 screen up or down difiicult.

Another important feature of the invention is a screen of the adjustable type in which means are provided for reliably guiding the members as they slide on each other to vary the width of the screen, and an improved means for limiting the extent of the outward movement of the sliding members, and at the same time permitting a maxinuun extension of the screen members as compared with known constructions.

Other important features of the invention, including details of construction and arrangements of parts, will be better understood from the following description, in connection with the accompanying drawings, in which.

"9 of the same screen.

The adjustable screen illustrated in ele vation in Fig. 1 comprises the two slidable members 1, 2, whose upper and lower pairs of rails 19, 21, have dove-tail tenons 3 sliding in grooves 4. These dove-tail guides extend substantially the entire length of the screen sections, and thus said sections are truly guided with reference to each other and the danger of sticking or imperfect slidable action is avoided. The tenon 8 is cut off or discontinued near the end of the rail 19, and in the space between the end of the tenon and the adjacent end of the rail 19 is located a pawl 14, pivotally mounted on a screw or pin 1%, the screw being located close to the end of the rail. The cooperating rails 21 are provided at their ends with shoulders 22, formed by making notches 22 in the lower sides of the grooves 4. as shown in Fig. 8. When the screen members are extended the distance of such extension limited by the engagement of the shoulders 22 with the pawls 14, as indicated in Fig. 6. The construction described affords a reliable means for stopping the movements of the screen sections, and by reason of the fact that the shoulders 22 are located at the outer extremities of the sections a greater amount of extension of the screen is permitted than would be. possiblewith the commercial form of adjustable screen in which the sections carry blocks, en-

gagement of which with each other limits the extension of the screen at such a. point that there is a considerable amount of overlapping of the screen sections, which is ob: jectionable,

The upper rail 19 of the screen section is provided with an angular inwardly extending strip 15, which overlaps the rail 21, the inner face of this strip lying flush with the vertical inner face of the rail 21 as shown in Figs. 9 and 10. The strip 15 closes the space between the adjacent face of the sash rail S and the rail 19, and prevents the entrance ol flies at this point. The use of the strip 15 is necessary in view of the fact that this screen is located between the sash guiding strips, or blind stops 13, 13, instead of being inserted inside of these strips, as is usual.

The outer edges of the side rails 01 the screen sections 1, 2 are provided with recesses 23 covered by plates 5 each of which has a slot 6 provided with a lateral opening 7, and headed pins or screws 8 are inserted at opposite points in the blind steps 13 for cooperation with said plates. The screws 8 are so located that they will occupy positions intermediate the ends oi the s 6 when the screen is in proper position. T insert the screen the openings 7 are placed opposite the screws 8, and the latter are caused to pass into the openings with the heads ot the screws inside the plates, and

received in the recesses 23, while the screen is in an inclined. position as shown in Fig. 3.- The screen is then swung into a vertical position.

At suitable points below the plates 6 the screen members are provided with reeesse. 24 covered by plates 12 having open notches 9 in one edge thereof, and headed stop pins or screws 10 are located in the strips 18 in position to enter he open notches with their heads back of the plates 12, when the screen is swung into vertical position. The stop pins 10 are so located that they will engage with the plates when the screen has beenmoved a suitable distance to cause the guide pins 8 to pass up into the slot G'as shown in Fig. 5. which illustrates the relative po sitions of the pins 8 and 10 in the plates 5 and 12. when the screen is in proper position in the window. When the pins 10 are locatedin the open notches 9 accidental movement otthe screen in the direction. of its len h, and hence disengagement of the pins 8 trons; the slot 6 is prevented until the screen is swung outward. The recesses or notches 9, accordingly. to the extent indicated. act as lockingmeans for the screen.

It will be observed that. the insertion and removal of the screen maybe easily accomplished; and that when inplace the screen will be locked againstremoval inany directionexcept by pullingthe screenback-wardly' into the room, so: asto tilt it as shown in. El 3. Itwill also be seen. that the screen when in. placeperinits-the sash be freely raised and lowered as the sash slidesinside of the screen instead of being arrested by engagement with the upper edge of the screen, as is usual with adjustable screens. A further advantage of the construction described is that tree access may be had to the space outside of the window by merely tilting the screen to an inclined position, and without removing it from its connection with the window. A still further advantage of this means of mounting an adjustable screen is that the heads of the screws 8, 10, will, by engagement with the plates, prevent accidental inward sliding of the screen sections when the screen is in place.

In the construction illustrated in Figs. ll and. 12 the form of plates and screws as shown in Figs. 4 and 5 is applied to a solid or non-adjustable screen, the arrangement of the plates 5 and 12, having the slots 6, openings "7, and openings 9' being the same as in the application of the invention to adjustable screens as heretofore described.

Changes may be made in the several parts described or in the details thereof, without departing from the principles of the invention, provided such changes or variations do not depart from the scope of the following claims.

I claim 1. A screen comprising a frame having recesses in its side rails, plates secured to the side rails over said recesses and provided with longitudinal slots hawing lateral openings, said side rails having recesses bc low the first mentioned recesses, and plates having open notches over said lower recesses, of headed pins in the window guiding strips located in position to enter the lateral openings in the firstunentioned plates and arranged to pass into the longitud'inal. slots in said plates, and other pins in said window guiding strips arranged to enter the openings in the last-mentioned plates to prevent longitudinal movements or the outward swinging ot the screen.

2. An adjustable screen comprising two relatively sliding members, dove-tail tongues and grooves in the upper and lower rails otthe frames of; said members,- the dove-tail tongues extending substantially the entire length of the rail of one of said members. a pawl pi-votaillv mounted to a face of the rail beyond sa id tongue, and a shoulder formed at the extremity of the groove for cooperation with said pa wls.

3. A- window screen comprising, incombination', two slidably adjustable sections; he upper and lower rails of one of said sections having dove-tail te'nons extending nearly to the end of said rails,- pawlspivotally 11'lOl111l38Cl',lIlsaidrails beyond said tenons, and the" upper rail having} an inwardly extending: st'rip arranged to" fit against the outer face of a; sash nail,- the upper and lower rails of the other screen sec tion having rooves to cooperate With said teams and sioulders at the extremities of said grooves For engagement by said pawls to limit the extension oi said sections, and opposite pairs of plates having slots and openings therein located at the outer edges of said sections at suitable distances apart, and headed screws arranged to be secured to opposite sash guiding strips in position for entering the openings and slots in said 10 plates to reinovably retain the screen sections in position.
